I'd like to know a few basic things regarding PHP. I know they must be available in the Net... but don't want to go searching for it.
- What exactly is PHP?
- What are the advantages/disadvantages fo PHP when compared to other server side scripts?
- If PHP scripts are inserted between HTML tags, will there be extra load on the server (as in the case of SSI)?
- Which is the latest version of PHP?
- Do we have to install a PHP interpreter in Apache server?
- How to use PostgreSQL with PHP? If I have PSQL already installed in my server, do I have to change anything if I install PHP also?
All comments welcome.
